Hi,
Thanks for your work.

1. OK – this will withdraw 1. If you replace the hamburger icon above products by a funnel icon, clarity and logic will improve for users.

2. that’s way, which works.

3. I will try to find an optimal with your guidelines. Though, I think that, for users, it would be far easier if the sub-categories were not only accessible when PRECISELY clicking on arrows, but also when clicking on text.

4. Looks like I was unclear, sorry. My point was about product counts, the number of products, how to withdraw them?

To illustrate my overall point, this is a view of boutique, on desktop this time, with 1. secondary menu used for product categories generated via menu; and 2. your title.

Which one is the most user-friendly, for you?
The advantages of the 2ndary menu:
– your can organize the menu like you need
– woodmart has more CSS settings options in menu than in page title
I can’t understand why you decided to have a non-working 2ndary menu on mobile

5. Your demo … I found why our experiences are different. My purpose was to try your demo on title / categories. Usually, I use firefox / developer tools. And when I click on title / categories, it does not work. But within Chrome, it does. I just tried on my mobile with firefox, and it works, so the issue is specific to firefox / developer tools. So, not a problem indeed.

Kind regards
